i This-invention relates to a fly exit attacha fiy exit attachment, in accordance with this' ment `for window and doorscreens, and has for'its object to provide, in a'rnanner as here-- W' inafter set forth, an attachment of the class Y'5 referred tocapable of being expeditiously connected to a screen to set up 'a thoroughly efficient flye'xit'.

' A'further object of theinvention'is to provide, in a manner as hereinafter set forth, a y fly exit attachment formed of two sections and havinginherent means for rconnecting themV to the screen in fly exitvposition ywithout the employment of solder. A further object of the invention is to provide, ina manner as hereinafter set forth, a fly exit attachment yfor connection to a screenl after the latterA has been installed in a frame, therebypreventingjthe screen from being loose or have a tendency to wave, the result being thatvthe screen willremain taut as wouldjnot be the case if'y they opening or openings in the screenwere cut prior to the installing of the screen within the frame.

` Further objects of the invention are to '25 provide, in a manner as hereinafter set forth,-

a' iy exitattachment which is simple in its construction and arrangement, strong, durable, compact, inexpensive, not marring, the appearance ofthe screen when attachedto the latter,quiclrly installed with respect to the screen, constructed in ya manner to overcome the'necessityof employing soldery for xedly securing the attachment to the screen,

thoroughly eiii'cientin its use, and inexpensiveY to manufacture.v f c ,c p' 'With the foregoing and` other objects'in .viewl the invention consists of the novel conf yz struction, combination and arrangement 1vof` .Y Q parts as ,hereinafter more specifically. de- 40"' scribed, and illustrated inthe accompanying drawings, Awherein is shown an embodiment of, the invention, but itis toy be understood thatchanges, variations and modications f. canbe resorted to which fall within the scope oftheclaims hereunto appended. f.

invention,installed with respectto the screen.

Figure 2 isa fragmentary view of a screen looking toward the inside thereof and further illustrating a fly exit attachment secured thereto and with one of the elements of the attachment broken away. v

y Figure 3 is a section'on line 3*-3 Figure 1. Figure 4 is a section on line 4-4 Figure l. A fly exit attachment, in accordance with this invention` includes an inner and an outer section indicated generally at 1, 2 respectively. The sections are'adaptedv to becon- Vnected to opposite faces of the screen 3 which is tofbeformed with apair-of spaced, rectangular slots 4, 5 disposed in lengthwise arrangement an-d extending transversely with respect to the screen 3. The edges of the slots or openings 4, 5 have points 6, see Figure 4,

p formed by the ends of the wires of the screen which are severed to form the slots or openings 4, y

Each section of the attachment is formed from a strip of sheet metal of the desired lengtlnwidth and gauge. Thesection 1 provides, in connection with the frame 3 a passage forming element. The passage, when section 1 is secured to the screen 3, leadsto the openings or slots 4, 5.

The section 1 includes a vertically disposed top part 7, a rearwardly directed, inclined part 8L which is of materially greater length than thev part 7 and gradually increases in width from its upper to its lower end. Extending forwardly from each side of the' part 3 is a triangular extension 9. As before stated, the section 1 in connection with the screen 'pro'vides a passage as indicated at 10 in Figure 3, and with the sidewalls of the latter provided by the extensions 9, the forward wall by the screen 3 and therear wall by the part 8. The passage 10` is open at its bottom andclosed at its top bythe point of joinder between parts 7 and` 8 as indicated at 11. The part 7 has its top edge formed with integral, upstanding, benda-ble coupling fingers 12 and each extension 9 hask its forward edge provided with spaced, bendable coupling lingers 13. The fingers 121 are employed for couplingv sections 1 and 2 to the screen 3 and the fingers in connection vwith fingers 12 the sectionv 2 13 are used for coupling the extensions 9 to the screen.

When section 1 is arranged against the inner face of the screen the part 7 abuts against the screen and terminates at its bottom slightly above the top edges of the openings 4, 5. The part 8 projects rearwardly from the screen V3. The iingers 12 are extended through certain of the interstices provided by the screen body and bent around section 2. See Figure 3. The fingers 12 are bent overthe top edge of section 2. The fingers 13 extend through certain of the interstices of the screen 3 and are bent against the outer face thereof. See Figure 1. f

The section 2 is formed of a rectangular body 14 of a length corresponding to the length of part 7 of section 1. The body 14 is of awidthin transverse cross section less than that of section 1. The body 14 is formed with two spaced sets of slits and the material freed by the slits is bent forwardly tol provide a pair of exit passages forming continuations of the openings or slots 4, 5. Each exit passageV has an uppery wall 15,7a lower wall 16 and a pair of end walls 17, 18. The walls 15, 16 extendtoward each other at aninclination and the end walls 17, 18 also extendtowards each other at an inclination. The walls 15, 16 have inclined end edges which are oppositely disposed and the end walls 17, 11S are of triangular contour. The setting up of the walls of each exit passagein the manner as stated provides a Vpassage which gradually decreases in height outwardly. The bends 19, 2O at the` points of joinder of the walls with the remaining portion of the'bo'dy 14 do not align with the points 6, but are arranged adjacent thereto so that the points will project beyond such bends. A' ,l Y

The'bottom edge of the body 14 is formed with a series of spaced, bendable, coupling fingers 21 adapted to extend through certain' of theinterstices'of the screen 3 and be bent against the inner faceof the latter whereby will be'secured against the outer face ofthe screen 3. f A f.

- The top edge of the body 14 isfo'rmed with a'series of spaced, bendable, coupling fingers 21 adapted Vto extend through certain of the interstices of the screen 3, over the top edge 1 and be bent against the rear face ofpart 7 of section 1 to secure'the sections together and to the screen 3.

rIhe section 1 is also what may be termed a directing element, due to the factv that it providesvink connection with the screen the passage V10 so that the iies will be directed toward the openings or slots 4, 5 and pass through the same into the exit passages 15.

The construction of the attachment enables it tobevexpeditiously secured to the screen, after the openings or slots 4, y5 are vplaced therein. The attachment is connected with the screen without theA employmentof solder and all that is necessary to do is to ,arrange the sections in the desired position and then bend the conpling fingers in the manner as illustrated and which iixedly secures the attachment against the outer and inner faces of the screen 3. Y n

Although the attachment is illustrated, by way of example, in connection with a screen,

with the section 1 positioned against the inner face thereof and thesectiOn 2 against the' other face, yet it is to be understood that the sections can be reversed in order to adapt the attachment to be used in connection with a fly trap. Y

It is thought vthe manyY advantages ofv a fly exit attachment, in accordancewith this.

inventionandfor the purpose set forth can Y be readily understood, and although the preferred embodiment. of the inventionV is as illustrated and described, yet it is to be understood that changes in the details of construe?,`
